SPECIFICATION forming part of Letters Patent No. 651,757, dated .l'un 12, 1906.

Application filed May 17,1899. Serial No. 717,166. (No model.)

T0 at whom it may concern.-

Be it known that I, HUGH HENRY, residing at Ennis, in the county of Ellis and State of Texas, have made certain new and useful Improvements in Bucksaws, of which the following is a specification.

My invention is an improvement in bucksaws, seeking to provide asimpl'e construction whereby to secure the saw-blade detachably in position and to tighten the same to any desired degree for operation; and the invention consists in certain novel constructions and combinations of parts, as will be hereinafter described, and pointed out in the claim.

In the drawings, Figure 1 is a side View of the saw ready for use. Fig. 2 is a detail view of the handle portion with the blade and loopframe detached. Fig. 3 is a detail View of the loop-frame. Fig. 4 is a detail view of the saw-blade detached, and Fig. 5 is an edge view of the outer end of the saw.

The loop-frame A is formed with, the top bar B, having at its outer end the bar 0, the latter forming one of the end bars of the sawframe, of which the handle D forms the other end bar. This handle D is formed with a metal plate E and the wooden bars E, covering the same, and at its upper end the bar E is prolonged to form or is otherwise provided B to a lug E projecting forward from the bar E, and a similar lug E projects forward from the bar E and is provided with an undercut bearing for engagement by thesawblade. This bearing is preferably a stud I, undercut at I, and a'similar stud 0 projects laterally from the bar 0 near its free end.

The saw-blade K is provided near its ends with openings K to fit over the studs I and 0 so that the saw-blade can be held in the under-cut portions of such studs when the latter are forced apart in the operation of tightening the blade.

In operation the arm F hasa slight spring or elasticity,so that it will permit the adjustment of the loop or connecting-ring over the end of such arm and along the same to tighten the saw=blade to any desired degree. When it is desired to remove the saw-blade for sharpening or for any other desired purpose, it is only necessary to press the arm F slightly toward the bar A and slip the ring or loop G off the free end of the arm F, when the studs 1 and (3 may be adjusted slightly toward each other to permit the removal of the blade. The blade may be replaced on the studs I and 0 when desired and the saw be again adjusted for use by slipping the loop G over the end of and up along the arm F to any desired position. It will be noticed the arm F inclines upward from its free end, so that the saw may be tightened to a greater or less extentby adjusting the loop G along the said arm as may be desired. a

It will be noticed that I avoid the use of all threaded straining-rods and provide a device for exerting tension which is simple, readily operated, and is not likely to get out of order. I

By means of the lever-arm F in the slidering G, I am able to exert great power in tightening the saw-blade. The construction of the bar E, with the lugs forming a pivot for the top frame and a support for the lug I and the lugs I and 0 forms a convenient means of connection of the saw-blade and avoids the necessity of rivets or similar removable fastenings.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A bucksaw comprising the frame having the top and end bars, the handle-bar pivoted to the top bar and having a lever-arm extended thereover and provided in its upper side with notches, the sliding loop or ring fitted over the top barand lever-arm and engaging the notches in the latter and the saw-blade substantially as set forth.

HUGH HENRY.
